It's crucial that I kind of keep up, without drifting into the backslapping land of cliche and lifetime achievement awards.

The whole idea of music, from the beginning of time, was for people to be happy

I realized what Led Zeppelin was about around the end of our first U.S. tour. We started off not even on the bill in Denver, and by the time we got to New York we were second to Iron Butterfly, and they didn't want to go on!

People have got to let their bodies breathe a little bit more. That's the great thing about being a pompous, jumped-up rock god. There's plenty of air around you.

Ten minutes in the music scene is the equal of one hundred years outside of it.

To rock isn't necessarily to cavort.

I love the feeling of letting fly, of pushing as far as I could go with my voice. The only way you can really graduate how you do it is by doing it regularly to people who don't have to be super impressed. You can do it in the studio all day long but you don't get the flashback that you get onstage.
